Well that didn't work

The organizers decide to ban race radios to make the stage more exciting, but they choose a dull, sprinter-friendly stage to do it. A break goes down the road, the teams eventually chase, the break gets caught in the final kilometers, Cavendish wins. I'm not sure what sort of improbability they were hoping would arise, but this stage was duller than any other sprint stage this Tour and with exactly the same result.
